Description

[Detailed description of the invention] The present invention relates to the structure of the edge reunit in an electric shaver. It lies face down, and when in use, it rotates 90 degrees and stands up to protrude horizontally, and is operated using an external operating member.

In this type of model, the present invention makes it possible to reliably hold the re-unit in both the stored state in which it lies down and the operating state in which it is raised horizontally, using a simple mechanism.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
FIG. 1 shows a vibrating electric shaver, in which a blade frame head 2 on which a shaving blade 1 is stretched is removably attached to the upper surface of a main body case 3, and a rectangular opening 4 is provided in the upper part of the main body case 3. , adjacent to this frontage 4 is a support shaft 6. which the reunit 5 is provided on its longitudinal side. It is rotatably supported at 6'.

This support structure will be described in detail later.

7 is the heir of the drive switch for the shaving blade 1 and the sharpening unit 5; 8 is the position where the sharpening unit 5 is housed as shown in Figure 3; 4. This is the operational descendant of the operating position shown in the figure.

In the edge resetting unit 5, a edge cutting blade 12 consisting of a fixed blade 10 and a movable blade 11 is attached to a support body 9, and a movable blade 1
1 is engaged by a drive member 13 - these drive members and the blade 10
．． A support fitting (not shown) is provided to prevent 11 from falling.

A one-shaped notch 13 is formed at the rear ends of both side walls 9' and 9' of the support body 9.

Reference numeral 14 designates an operating lever that moves up and down in succession with the operating knob 8, and the claw portion 15 at the tip engages with the cutout portion 13 of the edge reunit 5 to move the edge reunit 5 to the second position. It is freely rotated 90 degrees between the storage position and the operating position as shown in FIGS.

Now, to explain the shaft support structure of the above-mentioned rear unit 5, grooves 17 and 17 with openings 16 at one end are formed on the inner surfaces of both side walls 3' and 3' of the main body case 3, respectively, as shown in FIG. The support shafts 6.6' are inserted into the grooves 17.17 from the sides and locked therein.

In order to prevent the support shafts 6, 6' from coming out of the grooves 17, 17, retaining walls 19, 20 are integrally formed at both ends of the synthetic resin wall plate 18 separately provided inside the main body case 3. are in contact with the rear of the support shafts 6, 6', respectively.

Moreover, one of the retaining walls 19 has slits 21 cut therein to make it flexible and to be an elastic wall.

Further, the operating rod 14 is inserted into the gap between the support piece 22 that is lined up with the elastic wall 19 and the front wall of the main body case 3 so as to be smoothly guided up and down.

To explain the features of the present invention for holding the edge unit 5 in each state, which is rotated by the operating rod 14 to the storage and operating state, the above-mentioned The support shaft 6 on the side facing the elastic wall 19 has its peripheral surface removed and is shaped into flat surfaces 23 and 24 that intersect at right angles.

Therefore, when the edge-sliding unit 5 is lying down as shown in FIG. This stored state is maintained because the

On the other hand, when the operating lever 14 is lowered by the operating knob 8 from this state, the claw portion 15 causes the rear unit 5 to begin to rotate upward about the supporting shafts 6, 6'.

In this process, the elastic wall 19 bends backward, and when it has completely rotated 90 degrees, the tip surface 19' of the elastic wall 19 comes into contact with the adjacent flat surface 24, as shown in FIG. As in the previous case, a forward pressing force is applied to this support shaft 6, and the edge cutting blade 12 is reliably maintained in the operating state in which it protrudes horizontally.

Of course, at this time, the rear end of the driving member (not shown) of the edge cutting blade 12 engages with a suitable drive member in the main body case 3 and is reciprocated, causing the edge cutting blade 12 to vibrate.

As described above, according to the present invention, the support shafts provided on the longitudinal side of the unit are inserted into the grooves provided on the inner wall of the main body case, and each support shaft is At least one of the retaining walls arranged at the back is an elastic wall, and the cutting unit can be stored in a stored state flush with the case surface using the operating member, and can be rotated 90 degrees upward from this to hold the cutting blade. As a mechanism for reliably holding the supporting shaft in the operating state in which it protrudes horizontally, the circumferential surface of the support shaft facing the elastic wall is cut to form two flat surfaces, and the When the unit is rotated, the elastic wall articulately comes into contact with the unit, exerting a pressing force, and is stably held in each state.

Therefore, it is a very simple holding mechanism for the edge unit, and reliable operation can be expected, and its practical value is great.
